nope, no dumps. i have confirmed that my o/s options are set to create dumps, but there are none.

i guess this is to be expected because it is VirtualBox that is faulting, not the O/S.

when the crash happens i get a "VirtualBox.exe - Application Error" OK/Cancel dialog box in the host o/s that allows me to attach a debugger to the process. that is how i got the stack trace for the faulting thread.
